It will also have the full weight of the product with nutritional information. So dividing by no. of pieces should be easy.
I think Americans also tend to have larger formats for everything, so the calculations can sometimes be more tedious. Using the example of slices of bread, you would have to calculate how much are two slices compared to the whole pack to estimate their weight, and then you can know the nutritious values of your portion.

They also use a weird weight unit system, so everything isn’t easily divisible.
